Hi,

configure.ac sets extra_warnings with '-Wformat-non-literal', but you can
see that GCC does not understand this flag when the configure script runs,
and Clang gives warnings while building:
|  clang: warning: unknown warning option '-Wformat-non-literal';
|  did you mean '-Wformat-nonliteral'? [-Wunknown-warning-option]
|  warning: unknown warning option '-Wformat-non-literal'; did you mean
|        '-Wformat-nonliteral'? [-Wunknown-warning-option]

Would you mind to fix this?
